2.0 DESCRIPTION Detcon Model 10 single channel digital control modules are designed to supervise and display the status of a single remote gas sensor assembly. Modules are available for a variety of toxic and combustible gases. Model 10 Series control modules are designed to operate on an input voltage of 24 VDC and are compatible with a complete line of Detcon enclosures and mainframe hardware assemblies.

is to have the fault relay normally energized so that in the event of a power failure to the control module card, the fault relay will de-energize causing its relay contacts to change state, thereby creating a fault output. It must be noted that when an alarm relay is jumper programmed as normally energized, the contact outputs, normally open and normally closed, become reversed. The normally open contact becomes the normally closed and vice versa.
To enter the Program Menu press and hold the front panel switch for 10 seconds until the display reads Pr then release. Momentarily pressing the switch again after this will scroll through the program options.
2.4.7 Test Mode This function (tE) will cause a simulation of applying a full scale gas sample that will take the display through an incremental count up to the top of the range and back down, activating alarms at the programmed set points and allowing verification of alarm outputs, as well as the overange flashing feature. 2.5 POWER INPUT OPTIONS Standard operating input power of the Model 10 control module is 24 VDC unless 12 VDC is specified at time of order.

4. Alarm 1 is set to 20% of the default range. 5. Alarm 2 is set to 50% of the default range. 6. The RS-485 address is set to 01h. 2.10 CONTROLLER CALIBRATION The 4-20 mA output of the Model 10 control module is calibrated at the factory and should require no further adjustment. If under some special circumstance calibration is required, use the following instructions. To calibrate the controller you will need an extender card and have to be able to simulate a 4mA input and a 20mA input. 2.10.
